我有一个状态存储的对象数组，每个对象存储要用于渲染组件的值：
starting claim 4
spin: couldn't find claim 4 (ignored)
Starting Actor_a with pid 2
2: proc 0 (:init::1) sample.pml:30 (state 1) [(run Actor_a())]
Starting Actor_b with pid 3

7: proc 1 (Actor_a:1) sample.pml:14 (state 2) [((ch[0]>sz[0]))]
7: proc 1 (Actor_a:1) sample.pml:14 (state 3) [sz[0] = ch[0]]

我试图编写一个单击按钮时更新对象数组的函数。我已将按钮设置为调用函数const activeModal = [
{ modalName: 'dashboard', modal: Dashboard, active: true, icon: DashboardIcon, iconColor: 'black', iconBackground: 'white' },
{ modalName: 'memsline', modal: MEMsLine, active: false, icon: MEMsLineIcon, iconColor: 'white', iconBackground: 'black' },
{ modalName: 'mems', modal: MEMsGrid, active: false, icon: MEMsIcon, iconColor: 'white', iconBackground: 'black' },
{ modalName: 'events', modal: Events, active: false, icon: EventIcon, iconColor: 'white', iconBackground: 'black' },
{ modalName: 'people', modal: People, active: false, icon: PeopleIcon, iconColor: 'white', iconBackground: 'black' },
{ modalName: 'places', modal: Places, active: false, icon: PlaceIcon, iconColor: 'white', iconBackground: 'black' },
{ modalName: 'music', modal: Music, active: false, icon: MusicIcon, iconColor: 'white', iconBackground: 'black' },
{ modalName: 'movies', modal: Movies, active: false, icon: MovieIcon, iconColor: 'white', iconBackground: 'black' },
{ modalName: 'tvshows', modal: TVShows, active: false, icon: TVIcon, iconColor: 'white', iconBackground: 'black' },
{ modalName: 'games', modal: Games, active: false, icon: GameIcon, iconColor: 'white', iconBackground: 'black' },
{ modalName: 'settings', modal: UserSettings, active: false, icon: SettingsIcon, iconColor: 'white', iconBackground: 'black' }
]
openModal并按以下方式传递回onClick：
modalName但是，当我单击按钮时，没有任何反应。我期望发生的事情是，openModal = modalType => () => {
this.setState(state => {
const updatedActiveModal = state.activeModal.map(item => {
if (item.active === true) {
return {
modalName: item.modalName,
modal: item.modal,
active: false,
icon: item.icon,
iconColor: 'white',
iconBackground: 'black'
};
} else if (item.modalName === modalType) {
return {
modalName: item.modalName,
modal: item.modal,
active: true,
icon: item.icon,
iconColor: 'black',
iconBackground: 'white'
};
} else {
return item;
}
});
return {
updatedActiveModal,
};
});
};
对象数组已更新，以将当前活动的activeModal值更改为active，将false更改为{{1 }}和iconColor至'white'。它还应将单击的模式的backgroundColor值从'black'更改为active，将单击的模式false更改为true和iconColor到'black'并将所有更改保存到backgroundColor。我无法弄清楚我在做什么错，因为代码看起来应该可以工作。

我认为您只需要更改：
return {
updatedActiveModal,
};
到
return {
activeModal: updatedActiveModal,
};
